Answer:
initial magnetic field 1.306 T
Explanation:
We have given area of the conducting loop
Emf induced = 1.2 volt
Initial magnetic field B = 0.3 T
Time dt = 0.087 sec
We know that induced emf is given by
So initial magnetic field = 1.606-0.3= 1.306 T
Given mass = 2kg, height = 10m,g = 9.8.
We know that Work done W = FD
= > W = (mg)(D)
= > W = (2 * 9.8)(10)
= > W = 196 Joules.
Hope this helps!
Answer 4, liter
it’s not the same and it does describe volume
Answer:
-5.6m/s²
Explanation:
Given parameters:
Initial speed = 11.2m/s
Time of running = 2s
Unknown:
Acceleration of the puppy = ?
Solution:
Acceleration is the rate of change of velocity with time.
So;
Acceleration =
final speed = 0m/s
Acceleration = = -5.6m/s²
